Mechanics of Machining (Metal Cutting): Geometry of Single Point Cutting Tools

Geometry of single point turning tools Both material and geometry of the cutting tools play very important roles on their performances in achieving effectiveness, efficiency and overall economy of machining. Cutting tools may be classified according to the number of major cutting edges (points) involved as follows: • Single point: e.g., turning tools, shaping, planning and slotting tools and boring tools • Double (two) point: e.g., drills • Multipoint (more than two): e.g., milling cutters, broaching tools, hobs, gear shaping cutters etc. (i) Concept of rake and clearance angles of…
